This is an incomplete list of mines in British Columbia, Canada and includes operating and closed mines, as well as proposed mines at an advanced stage of development (e.g. mining permits applied for). Mines that are in operation are in bold.Past producers which are under reexploitation, redevelopment and/or repromotion are in italics.Also in italics are major projects under development or

With a slurrys natural pH is 9, it becomes clear Cu/Pb/Zn cannot be separated from each other nor from Fe. At pH 9 now, most of all metals would float. As shown here below, assuming Collector addition is Optimum, pH and MBS in the Copper Circuit drives Pb content in the Cu Conc.

The general decrease in apparent concentrations of Ba, Cu, Mn, Pb, Rb, Sr, and Zn produced by the addition of Fe, Ca, and Mg is shown in Figure 1. The suppression produced by Fe is greater than Ca, which is greater than Mg. The effect is generally greatest on Pb and Ba and least on Cu and Zn.
